[Casual Box] CasualBox Work Cap [Available in 2 Sizes / 5 Colors] Water-Repellent Hat Basic Mesh I bought this on Amazon a few years ago. It's new. The size is L, and it fits me comfortably, even though my head circumference is 62cm. The following is a quote from the Amazon description: [Recommended for Outdoors] A water-repellent work cap with a simple body and mesh fabric on the sides as a key point. With excellent water repellency, water beads up and repels well. Even after getting wet, the water droplets can be shaken off, and it can be easily wiped with a towel to return to its original state. It's great for outdoor activities such as camping and barbecues. [Size Selection Now Available] Available in two sizes: M and L. It's a BIG size cap hat that women and men can wear with confidence. The size can be adjusted with the belt on the back of the head, so people with small or large heads can wear it at the perfect size. [An Essential Item for Outings] The fabric inside the hat and the mesh fabric on both sides provide excellent breathability and are less likely to get stuffy. It's lightweight and can be compactly folded, making it a recommended rain hat that can handle sudden rain. [Supplement] The buyer, who has been involved in hat production management for over 20 years, manages the production from the materials to the sewing, so we deliver safe and secure products. It can be worn by both genders and all ages, making it a recommended cap for presents and gifts.
